+1 on reading and testing

As $this->sys_page->getRootLine is using a cache internally, performance 
should stay quite ok I think, although it'll create some additional 
overhead for every linked page on a site.

I wonder if we also have to adjust the method 
'getPageAccessFailureReasons' accordingly, as it's using 
"checkPageGroupAccess" internally but won't return the correct 
'fe_group' as it would return fe_group of the currently tested page and 
not the one probably found in the rootline.
